Detailsinfo

A vulnerability was found in Linux Kernel 5.0.0-rc7 (Operating System). It has been classified as critical. This affects the function ttm_put_pages of the file drivers/gpu/drm/ttm/ttm_page_alloc.c. of the component f2fs Filesystem Handler. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel 5.0.0-rc7 (as distributed in ubuntu/linux.git on kernel.ubuntu.com), mounting a crafted f2fs filesystem image and performing some operations can lead to slab-out-of-bounds read access in ttm_put_pages in drivers/gpu/drm/ttm/ttm_page_alloc.c. This is related to the vmwgfx or ttm module.

The weakness was released 12/31/2019. This vulnerability is uniquely identified as CVE-2019-19927 since 12/23/2019. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
